Firmware not flashing after hard reset.

[nikhil-robinson]

Was trying the launchpad with DIY options to flash my own firmware which uses esp32s3 usb serial example normal uplodas work fine but when i do rest device the decives boots up and cannot upload again i need to disconnect and connect my esp32s3 again.

Dev board esp32s3.

firmware :

static void initUart() {


    /* Disable buffering on stdin */
    setvbuf(stdin, NULL, _IONBF, 0);
    setvbuf(stdout, NULL, _IONBF, 0);

    // /* Minicom, screen, idf_monitor send CR when ENTER key is pressed */
    // esp_vfs_dev_usb_serial_jtag_set_rx_line_endings(ESP_LINE_ENDINGS_NONE);
    // /* Move the caret to the beginning of the next line on '\n' */
    // esp_vfs_dev_usb_serial_jtag_set_tx_line_endings(ESP_LINE_ENDINGS_NONE);

    /* Enable non-blocking mode on stdin and stdout */
    fcntl(fileno(stdout), F_SETFL, 0);
    fcntl(fileno(stdin), F_SETFL, 0);

    usb_serial_jtag_driver_config_t usb_serial_jtag_config;
    usb_serial_jtag_config.rx_buffer_size = 1024;
    usb_serial_jtag_config.tx_buffer_size = 1024;

    esp_err_t ret = ESP_OK;
    /* Install USB-SERIAL-JTAG driver for interrupt-driven reads and writes */
    ret = usb_serial_jtag_driver_install(&usb_serial_jtag_config);
    if (ret != ESP_OK) {
        return;
    }

    /* Tell vfs to use usb-serial-jtag driver */
    esp_vfs_usb_serial_jtag_use_driver();

}



static void Receive_callback(void *argument)
{

    // char buf1[1024]; // Assuming a maximum of 99 characters input
    int idx = 0;
    char ch;
    for (;;)
    {
        while ((ch = fgetc(stdin)) != EOF) 
        {
            stream_data[usb_offset] =ch;
            usb_offset++;
        }
    }
}

void usb_init()
{
     initUart();
    xTaskCreate(Receive_callback,"UART receive callback",4096,NULL,5,NULL); // receiving commands from main uart
    vTaskDelay(10);
    usb_offset =0;
}

void app_main()
{
        esp_log_level_set("*",ESP_LOG_NONE);
        usb_init();
        while (1)
	{
		printf("hello world\n");
		delay_ms(1);
	}
}
